When developing a dashboard, it's very useful to have access to a number formatting library. We should include one out of the box in CDF.
We have two choices:
2. CDO.dataFormat (part of CCC)
We should go with 2 as long as the formatting masks suffice and are in line with what the services team needs.
Regardless of the choice, we should build a simple accessor in CDF to format numbers and be consistent with its usage - something like $f(<number>, <format>)
